I don't know how resources are split in the QW team, but it's quite possible the guy doing the PBR work isn't the guy responsible for systems/gauge programming, so doing PBR wouldn't necessarily delay any fixes for Lnav etc.

The FSX Blue Angels F/A-18C Hornet is about the best you can get for free.
Don't worry about the "FSX" in the title, there is a P3dv4 version.
